learning that a computer glitch is putting the mars rover "curiosity" science experiments on a bit of a hold right now. nasa says it is still in contact with its good friend rover up there and hopes to have it fully functioning this week but it comes after "curiosity" made the most significant discovery yet that by confirming the red planet had the ability to possibly support some forms of life. that is what they're always looking for up there on the red planet. casey stiegel is checking out all of this in dallas. why do they think they believe life could have existed up there? >> reporter: hey, martha, good morning. biased primarily on the existence of water. scientists long thought it was on the red planet but only in the form of ice and now "curiosity" is essentially proving that theory wrong. they have discovered a ancient network of rivers up there have dried up but areas were formed by running water, possibly more than three billion years ago? the rover has been drilling down into the martian surface as well and finding elements like carbon, nitrogen and oxygen, things that living

, science experiments and hardware. just under three hours from now dragon should splash off of, baja peninsula about 250 miles. when it does that will conclude spacex's third successful trip up to the space station. bill: that is remarkable. is spacex going to skip the whole splashdown thing all together or not? >> reporter: that is the plan here in the next several years. the whole model for spacex on cheaper spaceflight is reuseability. eventually the plan is to have the dragon capsule leave the space station, descend down-to-earth and then drop and land safely on a landing zone on the ground, eliminating the need and cost of an ocean retrievallal. earlier this month, spacex successfully showed exactly how it will happen when one of its rockets made a 24 story hop up, hovered and gently touched back down. by 2015 spacex founder elon of course musk hopes to have actually people inside the coop suls going up to the space station. the u.s. lost that ability with the retirement of the space shuttle fleet. the only way up there for astronauts and cosmonauts is the russian soyuz capsule.
